Light-driven 'nanomachines' could be used as tiny missiles inside the body to blast away cancer cells

Scientists have created light-driven spinning molecules could become cancer-killing missiles.
In laboratory tests, researchers showed how the molecules can be activated by ultraviolet light to spin up to three million times a second and drill through cell membranes.
Another application for the tiny 'nanomachines' might be to deliver therapeutic medicines, researchers say.
HOW DO THEY WORK? The molecules can be activated by ultraviolet light to spin up to three million times a second and drill through cell membranes.
